離(li)心泵(beng)(beng)有很多(duo)不(bu)同(tong)的(de)(de)類型，對(dui)于不(bu)同(tong)液體(ti)需要選(xuan)(xuan)擇不(bu)同(tong)的(de)(de)離(li)心泵(beng)(beng)，液體(ti)粘(zhan)度不(bu)大(da)、流(liu)量(liang)較(jiao)大(da)、揚程不(bu)高(gao)(gao)時(shi)，宜(yi)選(xuan)(xuan)用(yong)往復泵(beng)(beng)；液體(ti)粘(zhan)度較(jiao)大(da)、流(liu)量(liang)較(jiao)小(xiao)、揚程不(bu)高(gao)(gao)或含有氣泡時(shi)，可選(xuan)(xuan)用(yong)旋渦泵(beng)(beng)；液體(ti)粘(zhan)度較(jiao)大(da)、流(liu)量(liang)較(jiao)小(xiao)、揚程較(jiao)高(gao)(gao)時(shi)，宜(yi)選(xuan)(xuan)用(yong)轉子泵(beng)(beng)。 理(li)解類型的(de)(de)選(xuan)(xuan)擇是最基(ji)本的(de)(de)，只有正(zheng)確選(xuan)(xuan)擇才能使(shi)得(de)正(zheng)常(chang)運轉，但是我們在使(shi)用(yong)中經(jing)常(chang)會遇到(dao)突(tu)然泄漏的(de)(de)問題，這又是哪些原因造(zao)成的(de)(de)呢？下面就來分(fen)析一下。 1、抽空、氣蝕(shi)或較(jiao)長時(shi)間憋壓，導致密封破(po)壞(huai)； 2、對(dui)泵(beng)(beng)實際輸出量(liang)偏小(xiao)，大(da)量(liang)介(jie)質(zhi)泵(beng)(beng)內循環(huan)，熱量(liang)積聚，引起(qi)介(jie)質(zhi)氣化(hua)，導致密封失效； 3、回流(liu)量(liang)偏大(da)，導致吸人管(guan)側容器(塔(ta)、釜、罐(guan)、池)底部沉渣泛起(qi)，損壞(huai)密封； 4、對(dui)較(jiao)長時(shi)間停(ting)運，重新起(qi)動(dong)時(shi)沒有手動(dong)盤車，摩擦副因粘(zhan)連而扯壞(huai)密封面； 5、介(jie)質(zhi)中腐(fu)蝕(shi)性(xing)、聚合性(xing)、結膠性(xing)物質(zhi)增多(duo)； 6、環(huan)境(jing)溫(wen)度急劇變(bian)化(hua)； 7、工況頻繁(fan)變(bian)化(hua)或調整； 8、突(tu)然停(ting)電(dian)或故障停(ting)機等。 當遇到(dao)突(tu)然泄漏的(de)(de)問題，我們一定要正(zheng)確分(fen)析，以采取對(dui)的(de)(de)措施，以免造(zao)成不(bu)要的(de)(de)損失。

水環真空泵一直非常關注粗糙真空的獲得，例如真空過濾，真空水轉移，真空蒸發等。它已廣泛用于工業生產的許多過程中。 為了節約能源，有必要盡可能地節約能源。我們如何使用水環真空泵來節能? 1. 水環真空泵對角安裝，以減小彎頭或蝸殼，使水口面向水池。 2.縮短水環真空泵管道，拆除1米長的鋼管，并在10小時內節省0.21千克柴油。 3.擴大水環真空泵的出口管直徑。例如，將15米長的4米長水管替換為15厘米長的管道，并節省10公斤柴油10小時。 4.如果可以保持進水清潔，則可以卸下水環真空泵過濾器。 5.?
